7.2.1 Applicable standards
According to FM Approvals Standards which can assure compliance
with Essential Safety Requirements
FM 3600: Electrical Equipment for use in Hazardous
(Classified) Locations, General Requirements.
FM 3610: Intrinsically Safe Apparatus and Associated
Apparatus for Use in Class I, II, III, Division 1, and
Class I, Zone 0 & 1 Hazardous (Classified)
Locations.
FM 3611: Nonincendive Electrical Equipment for Use in Class I
and II, Division 2 and Class III Division 1 and 2
Hazardous (Classified) Locations.
FM 3615: Explosionproof Electrical Equipment.
FM 3810: Electrical and Electronic Test, Measuring and
Process Control Equipment.

Maximum)
7.2.2 Classifications
The 2600T Series pressure transmitters have been certified by FM
Approvals for the following Class, Divisions and Gas groups,
hazardous classified locations, temperature class and types of
protection.
− Explosionproof (US) for Class I, Division 1, Groups A, B, C and D,
hazardous (classified) locations.
− Explosionproof (Canada) for Class I, Division 1, Groups B, C and
D, hazardous (classified) locations.
− Dust Ignition proof for Class II, III Division 1, Groups E, F and G,
hazardous (classified) locations.
− Suitable for Class II, III, Division 2, Groups F and G, hazardous
(classified) locations.
− NonIncendive for Class I, Division 2, Groups A, B, C and D, in
accordance with Nonincendive field wiring requirements for
hazardous (classified) locations.
− Intrinsically Safe for use in Class I, II and III, Division 1, Groups A,
B, C, D, E, F, and G in accordance with Entity requirements for
hazardous (classified) locations.
− Temperature class T4 to T6 (dependent on the maximum input
current and the maximum ambient temperature).
− Ambient Temperature range -40°C to +85°C (dependent on the
maximum input current and the maximum temperature class).
− Electrical Supply range Minimum 10.5 Volts, Maximum 42 Volts
(dependent on the type of protection, maximum ambient
temperature, maximum temperature class and communication
protocol).
− Type 4X applications Indoors/Outdoors.
For a correct installation in field of 2600T Series pressure transmitters
please see the related control drawing.
Note that the associated apparatus must be FM approved.
